Nowadays there are different routes that you can take for university.
Johnny sits exams in 3 A levels at the end of 2 years and gets 3 A stars, a UCAS point score of 168 and a place at an RG university.
Mary does a L3 Extended BTEC and at the end of 2 years of coursework is awarded DDD*, a UCAS point score of 168 and a place at the same RG university on the same course.
Johnny might be bright and lazy and knuckled down 2 weeks before the exams, but will probably have forgotten half of it by halfway through August.
Mary may have very poor working memory and processing speed issues that aren't a problem when she can do everything as coursework and take the time to get it right.
Which one is the best employee now?
